Just wanted to make a few comments.

First, Sages are obviously one of the most efficient researchers in the game. As others have pointed out, the only better (as in, more efficient) researchers (generally) are the Daughter of Avalon and the Philosopher. These are both capital-only commanders for a specific theme. Thus, you could argue that the Sage is the most efficient commonly-available (with exactly how available subject to change) researcher in the game. The fact that it is available on a random basis tends to make me believe it is too powerful.

The other point I would like to make is that there is no price increase for a commander being sacred. If he has priestly powers, he is charged for them, but not for simply being sacred. I found this out when I calculated the projected cost/actual cost ratio of all the mages in the game.
